MOLE-PLOW.

SPECIFICATION forming part of Letters Patent No. 376,674, dated-Tanuary 17, 1888.

I Application filed November 7,1887. Serial No. 254,540. (No model.) a

To all whom it may concern:

Be it known that we, THOMAS NOWELL and GEORGE H. WILSON, citizens of the United States, residing at Vilonia, county of Faulkner,and State of Arkansas, have invented certain new and useful Improvements in Mole- Plows, of which the following is a specification.

Our invention relates to that class of plows employed for draining wetlands by forming a sub-drain or duct without disturbing the surface of the soil; and it has for its object certain features of novelty in the construction of such implements, which will be first described,with reference to the accompanying drawings, and then more specifically pointed out in the claims. t

In said drawings, Figure 1 is a side elevation of a mole-plow provided with our improvements. Fig. 2 is a top view of the same.

In our invention the standard 1, to which the mole 2 is secured, is made very thin, and

has its forward edge sharpened, in order that i the implement may be used on lawns 01' other sodded grounds without marring the surface of the lawn by tearing ragged furrows through the sod and in order to make the traction of the implement more easy. This standard l-is around the standard is a metal or otherstrap, 7, which passes under the block 6, and passes diagonally upward through the beam and plate, and has its upper endscrew threaded, by means of which itis secured to the plate by a nut, 8.

On the underside of the beam and directly against the standard 1 is a block, 6. Looped It will be seenthat by tighteningthis nut the standard will be drawn against following is what we claim as new therein and desire to secure by Letters Patent:

The combination of the beam having an oblique perforation and a vertical, and downwardly-flaring slot, a plate secured to the. top of said beam and having a perforation and a slot corresponding, respectively, with the said oblique perforation and slot in the beam, a

colter passing through the slot in said beam 5 and plate and carrying a vmole at its lower end, a metallic strap looped around said colter, passing through the oblique perforationin said beam,and havingits end screw-threaded,

a three-cornered block interposed between said colterstrap and beam, and aunt on said strap for binding the colter in position, essentially as set forth.
